Can a SATA 3 HDD work on SATA 2 motherboard?
Can a SATA 3 HDD work on a SATA 2 motherboard? Yes it can, and you might not even notice there's anything wrong since the read/write performance of a hard disk is not bottlenecked by any revision of the SATA interface whatsoever.
Does SATA III work on SATA II?
SATA interfaces are backwards compatible, so the SATA II interface will function on SATA I ports, and SATA III interfaces are compatible with both SATA I and SATA II ports. However, there will be loss of sequential read and write speed rates when a newer SATA interface is hooked up to an older port version.
Can you connect a SATA 2 drive to a SATA 3 port?
Yes. FYI there is no difference between a SATA 1, 2 or 3 cable and SATA is backwards compatible. So the SATA 3 bus will knock down the speed to a SATA 2 standard (3/Gbps around 300 MB/sec) and you will be in business.
